I'm so glad I got into the beta, I can't get enough of the game. I've done the tutorials, and I've started playing some of the player created levels, and they are insane! Some are just plain goofy, but others are really creative and a nice challenge. Plus, with a grand total of an hour and a half playing online, I've already got a new friend; we had tons of fun going through some of the levels and smacking each other around.

On the technical side, I've had it freeze up on me for a few seconds, and when another person joins me (or vice versa), it gets really really laggy for a bit. Other than that, the game looks as good as I'd expect it to on my wonderful 480i TV, and the menu's are incredibly easy to navigate.

EDIT: I can't wait for this game!! =D

thats why its beta

I've now played over 80 different levels, and i'm having all the problems you are having and more. But i'm having alot more problems in the Socom beta so LBP is doing pretty good in comparison.

There are so many great levels to name all the ones you should try. But i would suggest "Colour the world" i think is its name. Another good one is some giant Pirate battle that takes place over many different ships and has a couple boss battles, it should be on the main cool page. The Sonic levels are pretty cool too, they are called "Green Hill" or something, they have 3 of them.

Some of the music ones are pretty cool too.

like many have said "beta test!"
